Excessive concentration of population into city has resulted in urban sprawl and environmental deterioration of suburbs in some cities. To prevent our cities from unfavorable situation of urban development, we are greatly in need of understanding of the city's growing appearance in the future. This paper examines an urban growth model of Jinju City. Existing urban growth models elaborated have difficulties in dynamic simulation. Easy geographic visualization and spatial exploration is another hard barriers to overcome. For these reasons we integrate Cellular Automate (CA) as an urban dynamic model and Geographic Information System (GIS) for visualization. Cell-based CA model was programmed with Visual C++ under the transition rules proposed with 1918 to 1986 growing trend of Jinju City. CA model constructed then was simulated as changing parameters into three cases. As a result, a CA model made was proved to regenerate urban growth as high as 93% of accuracy.

The Orthoptera and Hemiptera were investigated as a part of the survey to understand the ecosystem of Mt. Bongrae at the Islet Youngdo in Busan. Orthopteran fauna was consisted with 30 species belonging to 27 genera and 7 families. Acrida cinerea cinerea (Thunberg) was the most abundant species occcupying 13.58% in individual numbers. Hemipteran fauna was consisted with 58 species assigned to 53 genera and 16 families. Cletus punctiger (Dallas) was the most abundant species reaching to 22.70% of the total hemipteran individuals. The analysis of insect-communities suggested that Mt. Bongrae had poorly supported the insect groups for habitats and feeding ground due to low diversity of plants and fragmentation resulted by human interference. It was suggested to practice the restoration program to build up the ecological quality of the fauna on biogeographical and conservation principles.

p-형 Si(100) 기판 위에 성장시킨 Bi_(3.25)La_(0.75)Ti₃O_(12) (BLT) 박막의 전기적 특성

Bi₃zsLa(0.75)Ti₃0_(12) (BLT) thin film have been grown on p-type Si(l00) substrates by a sol-gel spin coating process. The structure and surface morphology of the film were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEMI. Furthermore, the electrical properties were examined by capacitance-voltage ( C-V) characteristics by using a LF Impedance Analyzer(HP 4192A). XRD measurement show layered perovskite structure with a single phase in BLT thin film annealed at 700C for 30 min in oxygen. The measured grain size of BLT on Si is about 0.04 - 0.1 pn. From the cross-sectional SEM image, BLT film thickness is measured to be 0.4 pm. The C-V characteristic hysteresis curves show that the NIFS (metal-fexroelectric-semiconductor) structure has memory effect. The memory window decreases, with increasing frequency at MFS structure. And it is found that the memory window increases as the applied voltage to the ferroelectric capacitor is increased. These phenomena may be due to polarization reversals of the BLT ferroelectric film and because of the charge injection from Si substrate into the ferroelectric thin film. The results obtained indicate that the present BLT films are suitable for making ferroelectric field effect transistor(FeFET) memory.

Conflicts between human and polispine wasps have been reported during a recent few years. It was, therefore, investigated the species diversity and distribution of the polispine wasps inhabiting at the Islet Youngdo. Parapolybia indica (Saussure), Pa, varia Fabricius, Polistes chinensis antennalis Perez, P. jadwigae jadwigae Dalla Torre, P. japonicus japonicus Saussure, P. mandarinus Saussure et Geer and P. snelleni Saussure were recorded. they ard aggressive against human approach bur lesser than vespine wasps. As a consequence of the successive works to vespine wasps, polispine venoms were discussed for their toxicity, allergy, damage and preventive caution. Contrary to their harmfulness, it was also proposed to conserve the polispine wasps respecting their useful ecological niches, but within maintaining at least the minimum viavble populations as well as the numbers of inhabiting sites within the islet.

영도산 생물다양성의 분류학적 측정과 도시생태학적 평가 Ⅱ. 벌목

부산 영도 봉래산의 생태계를 이해하기 위한 일환으로 벌목에 대해 조사를 하였다. 봉래산에서 총 13과 101속 123종이 조사되었는데 그 중 점박이 땅벌이 13.14%를 나타내어 우점종을 나타내었고 그 뒤로 말벌, 장수말벌, 좀말벌, 곰개미가 따랐다. 따라서 봉래산에 서식하는 벌목 중에서 말벌과에 속한 종들이 우점군을 차지하고 있는 것으로 나타났다. 이는 봉래산의 식생이 빈약하기 때문에 식생의 영향을 많이 받는 맵시벌과나 꿀벌과에 비해 말벌과가 적응도가 높은 것으로 보인다. 그래서 봉래산에 있는 벌목의 종다양성 확보를 위해서는 봉래산 실정에 맞는 생태적인 질의 향상을 모색해 알맞은 장소에서 복원을 해야 할 것이다. Insects may provide the important clues related to human death. The insects are a good substitute to traditional materials for forensic analysis to estimate postmortem intervals and location of bodies. In case of decayed or dried remains, it is difficult to carry out precise analysis in traditional materials as muscles or internal organs decayed, while insects feeding on cadavers may be appropriate for the analysis. Various toxins and drugs were discussed for their impact on insects and their fates in insects in forensic aspects of view.

본 논문에서는 Mach-Zehnder 간섭기로 구성된 1×4 필터와 성형결합기로 구성된 5×5 광도파로 격자 라우터를 BPM CAD TOOL을 이용하여 설계하였고 최적화 하였다. 마스크 레이아웃을 효율적으로 실현하기 위한 전체 도파구조를 설계하였다. BPM 전산모사를 통해 설계된 소자의 WDM 특성을 0.8 nm(100 ㎓)와 8.0 nm(1000 ㎓)의 채널간격에 대해서 살펴보았다. 설계된 소자는 두가지 채널간격 모두에 대하여 3.5dB 이내의 잉여손실, 0.5dB 이내의 균일성과 -22dB 이내의 누화(crosstalk)특성을 보임을 확인하였다. In this paper, we designed and optimized 1×4 WDM Filter composed of Mach-Zehnder Interferometer and 5×5 Waveguide Grating Router(WGR) composed of two star couplers. The overall guiding structure is designed to realize the mask layout efficiently. Through the BPM simulation, we demonstrated WDM characteristics of these devices with 0.8 nm and 8.0 nm channel-spacing. It is shown that the excess loss is less than 3.5dB, uniformity less than 0.5dB and the crosstalk smaller than –22 dB for both the channel spacings.
